Letters Patent No. 79,832, dated July 14, 1868.

IMPROVEDMAGHINB FOR WASHING LEATHER.

TO ALL WHOM IT MAY CONOERN;

Be it known that we, ADOLPHUS HOWARD, ofiWellsville, in the county of Allegany, and State of `New York, and GEORGE F. HOWARD, of the city1 of Chicago, county of Cook, and` State of Illinois,'(assgnors tothe said GEORGE F.` HOWARD have invented a new and useful Improvementin Machines for Washing Leather, for' use in tanneries; and we do hereby declare that-the following is'a full, clear, and exact description thereof, reference being had tol the accompanying drawings, makinga part of this specification, in which- A Figure I is a sectional side elevation. i

4Figure II is a` transverse vertical section.

The nature of this invention consistsi 1. In the application and use of splint brooms in a machine-for washing leather.

2. In the manner of attaching said splint brooms to a revolvingshaft o'r shafts.

lLetters of' like name and kind refer to like parts'n each of the figures.

Thisinvention being an improvement in the construction of a machine for washing leather, for which Letters Patent of the United States were granted to ns on the twenty-eighth day of May, A. D. '1867, for a particular description of such parts of said invention, .shown' in the accompanying drawings, but not claimed in specification annexed to said Letters Patent, reference is hereby made' to the Letters atent aforesaid. i

` A brief recapitulation of those parts is,.therefore, deemed suicient for 'thepurpose of this application.-

O, frame of the machine. i

H, cover.

B B, water-tanks.

I, pump.

A A represent a series of splint brooms, whichiareV attached tothe revolving shafts G by means of the Tadialarms or disks, C, and adjusting-clamps 'D D'. i There may be one, two, or more sets of brushes secured to an equal number of arms, using the same numberl of clamps for that purpose.

Each clamp consists of the stationary 'board D, firmly attached to the radial arms O, and a removable board D', adjusted with a set-screw or bolt, d2. The splint brooms are placed between the two boards, and held firmly therein by the set-screw. E represents gearing, and F the main driving-pulley. I

Splint brooms have heretofore been made and used for removing the sediment remaining upon a side of leather (after it has been vremoved from the vat) by hand; and since this manual labor has been 'superseded by the use of a revolving brush, driven by suitable machinery, the splint broom was abandoned and a hair-brush substituted, on account of its simple construction and mode of attachment. y

Upon making practical experiments with our machine for washing leather, patented May. 28th, 1867, we discovered that brushes, to lbe used for scrubbing leather bymaehinery, might be made of the same material used for brushing by hand, and 'with a better result, especially that one of the revolving brushes', which scours the iesh side of the leather, shl'd'be composecl'of splint brooms, or an equally hard and stout material. Hcnoev What we claim as our invention, and desire to secure by these Letters Patent, is-v 1. In a machine for washing leathcrthe application and use of splint brooms, substantially as and for the purposes herein' described,

2. In a machine for washing leather,tlie Aclamps D D', or its equivalent, in'ombination with the radial arms or disks C upon the shaft G, for the purpose andsubstantiallyas described.
